A further object of the invention is the provision of visible dispensing apparatus, combined with-means for providing circulation of air and maintaining visibility.

Other objects of the invention will appear hereinafter, the novel features and combinations being set forth in the appended claims.

In the accompanying drawings- Fig. 1 is a sectional elevation of an oil fountain embodying my improvements;

Fig. 2 is a horizontal sectional view taken on the line 22 of Fig. 1 looking upwardly as indicated by the arrows;

Fig. 3 is a. sectional elevation taken on the line 3-3 of Fig. 2 looking in the direction of the arrows and showing the upper visible portion of the fountain shown in Fig. 1;

Fig. 4 is a wiring diagram to illustrate the control of the heating elements embodied in the structure shown in Fig. 1;

Fig. 5 is a plan view of the drip receiving means with the drip cups omitted; and

Fig. 6 is a sectional elevation of the canopy with the plate of Fig. 5 locked thereto.

In Fig. 1 is shown a base 7 on which is mounted a housing 8 lined with asbestos 9. On top of the housing 8 is mounted the basin 10 which is provided with the chamber 11 surrounding the central tubular support 12.

Extending from the upper central portion of the support 12 is another tubular support 13 of smaller diameter than the support 12. At the upper end of the tubular support 13 is a circu-' lar seat 14 for the glass cylinder 15. As shown in Fig. 3, the lower end of the glass cylinder 15 the same manner as the lower end is hermetically sealed from the support 13.

Extending through the central portion of the base '7 into the housing 8 is a plurality of oil supply pipes 19. In th. structure shown four such supply pipes are included, one for each of the four glass tubes shown at 20, 21, 22 and 23 in Fig. 2.

The upper ends of the tubes 20, 21, 22 and 23 are connected to oil delivering passageways under the canopy 18. For the sake of more clearly illustrating the structure a section of Fig. i is taken from the front diagonally at 45 to the center and then horizontally toward the right. The passageway in the canopy 13 for the tube is shown at 24 in Fig. 1. The casting 25 which has therein the oil duct or passageway 24 may be integral with or rigidly secured to the canopy 18. To the discharge end of the oil duct 24 is connected a nozzle 26 having a valve controlled by the manually operated device 27. The nozzle assembly 28 may be secured to the casting 25 by means of the bolt 29. In a similar manner the bolts 30 may be relied on to clamp the union 31 to the bottom of the tube 20. The union 31 may be integral with the casting 13, 14. The pipe 19 shown at the left of Fig. 1 may be connected to the union 31. It will thus be seen that when air pressure is exerted on a supply of oil in a distant tank connected under ground to the pipe 19, the opening of the nozzle 26 by means of the handle 27 will permit oil to be dispensed into a container held beneath the nozzle.

Within the space between the four transparent oil tubes 20, 21, 22 and 23 is located an electric lamp 32 preferably extending the full length of the tubes as shown in Fig. 1. Between each oil tube and the next adjacent one is an opaque guard plate held in place by a vertical rod. Between the oil tubes 20 and 21 is a guard plate 33 held in place by the rod 34. Similar guard plates are shown at 35 and 36 held in place by the rods 37 and 38 respectively. Between the oil tubes 22 and 23 is the electric conduit 39 with strips of opaque material bent back on themselves between the pipe 39 and the tubes 22 and 23 as shown at 40 and 41 in Fig. 2. Therefore when the current is turned on the electric lamp 32 the light therefrom will be obstructed by the guard plates 33, 35 and 36 and by the opaque pipe 39 .and the opaque fillers 40 and 41. The oil tubes 20, 21, 22 and 23 are always full of oil. A plurality of tubes are useful for the purpose of serving difierent grades and qualities of motor oil and it is desirable to have the illumination extend through the oil in the transparent tubes so that the oil in these tubes will be clearly visible individually without being confused with the oil in the other oil tubes.

Within the housing is an auxiliary housing 42 surrounding the supply pipes 19. The lower end of the auxiliary housing 42 opens into the chamber 43 in the housing 8 but the upper end is connected to the lower end of the tube 44 which is spaced from the inner wall of the tubular support 13 to afford an annular chamber 45. It should be understood that the upper end of the tube 44 communicates with the bottom of the chamber 46 which is formed by the vertical guard plates which engage the sides of the oil tubes 20, 21, 22 and 23 as shown in Fig. 2.

Within the auxiliary housing 42 are mounted two separate electric heating elements 47 and 48 by being connected by means of the clamps 49 and 50 to the pipes 19. The lower electric terminal for the heating element 47 is shown at 51. The terminals for the heating element 48 are shown at 52 and 53 in Fig. 1.

In Fig. 4 is shown a wiring diagram of the electric circuits and connections for the incandescent lamp 32 and the two heating elements 4'1 and 48. When the main line switch 54 is closed the supply mains 55 are connected to the wires which may be led underground from the building at a filling station to the oil fountain located distant therefrom in a convenient position for use and service to motor cars. The wire 56 may lead underground directly from such building to the conduit 39 leading upwardly through the base '7 and the housing 8 to the junction box 57 and thence directly to one terminal of the incandescent lamp 32 and to one terminal 51 of the heating element 47 and one terminal 52 of the heating element 48. In the other'circuits 58, 59 and 60 which also lead directly from such building underground to the oil fountain and to the junction box therein there may be located manually operated switches 61, 62 and 63. The conductor 58 is connected to the lamp 32 and therefore when theswitch 61 is closed the lamp 32 will be lighted up. When the switch 62 is closed the heating element 47 will be operated. The circuit for the heating element 4'1 may be traced from the switch 54 through the conductor 56, junction box 57, terminal 51, resistance of the heating element 4'7, conductor 59, switch 62, back to the other side of the switch 54. When the switch 63 is closed the heating element 48 will be operated, the circuit being through conductor 56, junction box 57, terminal 52, resistance of heating element 48, terminal 53, conductor 60 and switch 63 to the other side of the supply mains 55.

When the electric lamp 32 alone is operated the heat produced thereby may be suflicient in inclement weather to produce a circulation of air from'the lower open end of the auxiliary housing 42 through the tube 44 and thence through the passageway 46 to the chamber 64 in the canopy 18. The air will then pass downwardly through the openings 65 into the passageway 66 which surrounds the oil tubes as shown in Fig. 2. The tube 44 being spaced from the interior wall of the tube 13 the air will continue downwardly through the passageway 45 into the chamber 43 of the housing 8 and thence back into the bottom of the auxiliary housing 42. When in addition to the lamp 32 being lighted up, the switch 62 is operated to turn on the heating element 47, greater heat will be produced to keep the oil in the pipes 19 and the oil tubes 20, 21, 22 and 23 sumciently warm to decrease the viscosity to permit free flow. In the coldest weather the heating element 48 may be turned on by means of the switch 63 in addition to the heating element 47 and the lamp 32. During the day it may not be desirable to turn on the lamp 32 and regulation of the temperature of the oil may be secured by means of the switches 62 and 63. Even without the use of the lamp 32 and/or the heating units 32, 42 and 48, the arrangement of the associated elements of my pedestal and especially the arrangement of the inner tube 42 connecting with the glass containers 20 and the concentrically surrounding transparent cylinder 15 providing inner and outer passageways, it must be apparent that a natural circulation will be provided so that in cold weather the hotter air enclosed by the more protected or lower portions of the pedestal will rise upwardly through tube 42 and will circulate through the space between the glass containers 20 and will pass upwardly and upon being chilled will thence pass downwardly through the aperture 65 and through the space between the outer glass cylinder 15 and the ring of glass containers, and thence downwardly into the base of the pedestal again, recirculating in a natural manner. Obviously when either the lamp 32 is used or the heater or both, this air-circulation is considerably augmented. In any event the glass cylinder 15 and the inner glass containers are kept clear so that the oil in the containers 20 is visible upon the outside. This arrangement of containers and outer cylinders, including the provision of a natural circulation in and about the glass cylinders and through the outer cylinder, is of great advantage.

In order to retain as much as possible of the heat which has been generated and to provide insulation against cold from the outside, the oil pipes in the base 7 are packed with rock wool 67 and the canopy 18 is packed with rock wool 68. Other insulation, preferably of a fibrous nature, may be substituted for the rock wool. The housing 8 is lined with asbestos 9. The glass cylinder 15 not only provides the outer passageway 66 but also assists in serving as an insulation against cold from the outside entering the vertical oil tubes. That is to say, the large display glass cylinder 15 in which the smaller display oil tubes are located completes the protection of warm air circulation from outside temperatures during its entire progress through the fountain.

Attached to the lower end of the tube 44 are radial brackets 69 in which is mounted a wire basket '70 for containing calcium chloride '71 for the purpose of removing all moisture from the air which flows down through the passageway 45 into the chamber 43 in the lower housing 8. The removal of the moisture from the atmosphere within the dispensing unit further increases the efficiency of the heating units 32, 47 and 48 and prevents the accumulation of moisture within the large glass display cylinder 15 and on the outer surfaces of the oil display tubes 20, 21, 22 and 23. At the periphery of the basin 10 is a ledge or seat 72 for receiving the grid plate '73 when in its lowermost position. As shown in Fig. 5, this grid plate is provided with a large circular opening 74 in its center of suiliciently large diameter to have ample clearance when lifted over the upper edge of the tube 13 and below the casting 75 within the canopy 18. The grid plate 73 is also provided with a plurality of perforations 76 to permit such oil as may be spilled to flow back into the basin l0. Accumulated oil in the basin 10 may be removed by withdrawing the screwthreadedfplug 7'7 shown in Fig. l.

The grid plate '73 is also provided with a plurality of openings 78 each having a peripheral seat '79 for receiving the upper peripheral flange 80 of the drip cup 81. There are four drip cups provided for the four openings 78 in the construction shown. Each of these drip cups is separately and independently removable from the grid plate 73 for the purpose of separately emptying the drip cups, or each cup may have a drain hole in its bottom.

When the grid plate 73 together with the four drip cups 81 suspended therefrom are lifted with the central circular opening '74 moving over the tube 13 and over the lower end of the casting 75, the grid plate '73 may be tilted so as to enable one side thereof to be placed over the lug 82 on the inner side of the canopy 18 as shown in Fig. 1 and also in Fig. 6. On the opposite side of the canopy 18 as shown in Fig. 6 is located a hasp 83 over which the opening 84 in the grid plate 73 may extend so that a padlock 85 may be used to lock the grid plate in its uppermost position with the drip cups 81 covering the four dispensing nozzles as well as the handles for operating the valves connected to the nozzles. In other words, the locking of the grid plate together with the drip cups in uppermost position renders the nozzles and the nozzle control devices inaccessible and prevents operation by unauthorized persons.

The canopy 18 may be removably mounted on top of the dispensing unit so that inspection of the insulating material 68 may be had and replenishment thereof made, if desired. The lamp 32 may also be renewed. For this purpose the casting '75 may be made separate from the canopy 18 and mounted directly on the glass cylinder 15. The cap plate 86 may be used to clamp the casting 75 to the top of the glass cylinder 15 by co-action with nut 8'7 on the conduit 39. The canopy 18 may be secured to the cap 86 by means of the cap screw 88. The oil conduits 25 may each be separate and independent of the casting 75 and the conduits .25 may be separately secured to the tops of the oil tubes by means of the tie rods 30. The packing of the insulating material 68 may be made more effective by providing the vertical walls 89 and 90, the latter being secured to the casting 25 as shown at 91 in Fig. 1; 91 designates also a manually operated valve for removing entrapped air in the oil duct 24.

An electric light socket may also be provided at 92 for an electric lamp connected in parallel with the one designated 32. The electric fixtures for the sockets 92 and 93 are connected rigidly to the upper central portion of the canopy 18. By means of the spaced set screws 94 the canopy may be leveled and long electric light bulb 32 may be centralized within the chamber 46 between the various oil tubes 20, 21, 22 and 23, and after this has been done the canopy may be rigidly connected to the cap 86 by means of the cap screw 88.

It should be particularly noted that the various grades of oil are always on display since the supply tubes 19 and the transparent tubes 20, 21, 22 and 23 are always maintained full of oil. The electric heating and air circulation arrangement is for the purpose of maintaining the oil of such consistency as to flow freely when the oil fountain is located outside distant from a filling station building. The serving of the oils is therefore centralized at one convenient point where the oil fountainunit is located.

Obviously those skilled in the art may make various changes in the details and arrangement of parts without departing from the spirit and scope of the invention as defined by the claims hereto appended and I wish therefore not to be restricted to the precise construction herein disclosed.
